Abstract
A hybrid vehicle and operating method, wherein, given a pending change in the rotational speed of a combustion engine of the hybrid vehicle, provides for a battery, independently of the power to be transmitted to the driving wheels, to be so charged or discharged in a directed manner that the change in rotational speed is effected as swiftly as possible. With regard to fuel consumption, pollutant emission and/or care of the engine, optimal operating points are passed through. On the one hand in the case of a pending increase in power of the combustion engine, it is provided for the battery to be more heavily discharged or less heavily charged according to the initial situation, and in the case of a pending reduction in power, to be more heavily charged or less heavily discharged.
